wherein the determining criteria of the seat module is: comparing the Web access service beginning message sent by the CTI with the instant messaging request sent by the instant messaging module, and, if it is indicated that the instant messaging request is a legitimate message by comparison, notifying the instant messaging module to accept the instant messaging request;

(5) after accepting the session request, the seat notifies the CTI to set the state of the seat being in service through the seat module; the CTI refreshes the state of the seat, does not accept other access requests of accessing the seat any longer and notifies other modules such as a log server of the call center platform to perform corresponding processing, such as recording a service log, a session start time and the like;

(6) the user and the seat then can begin an online chat directly with their accounts in the instant messaging system as identifiers; and

(7) the user and the seat can further initiate other extended services supported by the instant messaging system, such as video chat, video conference, white board, application program share, remote assistance and the like; the customer service representatives can serve the accessed users by various interaction modes.

The above process is the process that a user initiates the instant messaging request to a seat; the session access process of the system will be described briefly below:

(1) the Web access module initiates a session call access request to the seat based on the session call access operation of a user, and sends the CTI call queuing information of the user including the call number of the user; wherein the Web access module preferably sends the session call access request to the seat through the soft switch and the intelligent network SSP;

(2) the CTI allocates an idle seat to the user according to the received call queuing information;

(3) after the CTI allocates the idle seat, the seat accepts the session call access request sent by the Web access module via the soft switch and the intelligent network SSP, and performs a session; and

(4) after accepting the session call access request, the seat notifies the CTI to set the state of the seat being in service, the CTI refuses other access requests of accessing the seat.
